A Reaction

A part from the emphasis on powers, this sounds a bit like Armstrong's account, that laws are the necessary connections between properties. It is scientific essentialism because Locke expects researchers to discover this stuff.

15223 Necessary effects will follow from some general theory specifying powers and structure of a world [Harré/Madden]
